(or. 2er-s1) 4 Claims.

My invention relates to powder dispensers and refers particularly to dispensers of the mentioned character from which powder may be expelled in a ne spray like dust condition.

One object of my invention is unitary devices adapted for the reception of a powder, means allowing its emission in the form of a fine spray and means for expelling the powder therefrom.

Another object of my invention is devices having the .properties mentioned without the diiiculties incident to plunger types of devices fo'r similar uses.

Another object of my invention is powder spraying devices operatable with one hand.

Among the other objects of my invention are powder dispensing devices of economic construction, having a minimum of moving parts, ease of operation, and certainty of desired results.

The above-mentioned, and other, valuable attributes of the devices. of my invention will be v evident upon a consideration of my speciiication and its accompanying drawings, in which similar parts are designated by similar numerals.

Figure l is a perspective view of one form of a device of my invention.

VFigure 2 is a top view of the device of Figure l before the top cover is applied, partly in section. Figure 3 is an enlarged section through the line 3- 3 of Figure 1.

Figure 4 is a top plan view of the blank from which the bodyportion of the device of Figures 1, 2, and 3 may be produced.

Figure 5 is a top plan View of the top cover showing a modified form of closure meansfor the powder exit opening. l

Figure 6 isv a side view of a modified form of a device of -my invention partly broken away for purposes of description.

Figure 7 isa side view of the inner element of the body of the device shown in Figure 6.

Figure 8 is a section through the line B- of Figure 7.

Figure 9 illustrates a. means for operating the devices of my invention.

The device of my invention shown in Figures l to 4, inclusive, comprises a blank lamina i0 having a plurality of parallel openings il, Il, forming the upper continuous member i2 and the lower continuous member i3.'

The lmina i0 may be made of paper, cardboard, or other material having the physical properties necessary for the production of my devices as will be evident from the uses -to which my devices are applied.

In the production of my devices the lamina l0 is wound upon itself, forming a desired nurnber of convolutions, dependent upon the propery ties of the vmaterial from which it is formed, as

shown particularly in Figure 2.

'Ihese convoluted layers' are firmly affixed to by a plurality of unitary strengthening uprights formed by the convolutions of the portions of the lamina l0 between the openingsl I, il.

A label, or outside covering, I4 is then xedly attached to the outer face of the body member by glue, or other suitable adhesive, thus enclosing the device and acting as a means for retaining powder in the device..

Thev bottom imperforate cap I5 is crimped upon one end of the cylindrical body by any suitable means, and the top cap I6, having a powder exit opening Il therein, is crimped upon the other end of the cylindrical body by any suitable means.

A closure member I8 for the opening Il in the form of a suitable flexible material is then attached to the top cap i6 and covering the opening i7;

The modiied form of a device of my invention shown in Figures 5 to 8, inclusive, comprises a tubular member 20, formed of cardboard, paper, or other suitable material, has a plurality of parallel openings 2l, 2|, with the top member 22 and the bottom member 23. A bottom cap 24 is crimped thereon'by any suitable means and the top cap 25 having a powder exit hole 26 therein for retaningpowder in the device.

It will be noted that the body member comprises the top unitary strengthening member 22 and the bottom unitary member 23 connected by the unitarial strengthening uprights formed by that portion of the tubular member between the openings 2|, 2|.

The devices are operated as shown in Figure 9. The central portion of the device is grasped by the hand and compressed, the powder being thus expelled, or forced, outwardly through the powder exit opening, as indicated, the release of the pressure upon the central portion of the body allowing the body portion to expand outwardly and assume its original and natural-position.

A consideration of the uses to which these devices are applied, and of the operation whereby these desirable results are obtained, will indicate the character of the material which must be employed in their production, as well as the value of devices of the described construction for the purposes for which they are intended.

It is evident that the material of the body and the outside cover, must be such that it will not be aiected by moisture, and, that it must be practically moisture proof in order to protect the enclosed powder, it must be of such thickness and composition as to be compressible-and resilient enough to recover its natural position upon release of such pressure.

As, in the ordinary cap crimping machinesl considerable longitudinal pressure is exerted upon the cylindrical body in order to position and maintain the body during the crimping process, it is further evident that the body must be of such strength as to allow of this longitudinal pressure.

Further, for commercial reasons, the devices must be inexpensive in production, easy of operation, and not liable to become inoperative. If the walls of an imperforate cylindrical body portion are thick enough to withstand the longitudinal pressure of a crimping machine, they are usually so thick as to make the desired compression impossible, and if they are thin enough to allow of compression they are usually too thin to withstand the longitudinal pressure of a crimping machine.

Further, if the walls are thick enough to withstand the longitudinal pressure of a crimping machine, they are liable to dent in and creasev when pressed inwardly, instead of taking an arclike shape, and hence, do not have Lufcient re siliency to recover to their original form.

It will be noted, however, that the body lof myl of the employment of thicker materiall with re-i silient compressibility than is possible where' the cylindrical body wall is of one piece.

I do not limit myself to the particular described number, arrangement, shape, or material of parts, as these are given solely in order A,to explain the devices of my invention. l

What I claim is:

1. A laminated compressible powder dispensing device comprising a laminated body wall formed of a sheet of compressible substantially resilient material having a plurality oi substantially parallel, longitudinally positioned elongated openings therein, said openings being so spacedwith respect to each other that they will form said wall with a plurality of openings therethrough; end closures carried by said wall, one of said closures having means allowing the emission of containedY powder therethrough; and a iiexible outside covering for said device closing said wall openings'.

2. A laminated compressible powder dispensing device comprising a laminated body wall formed of a sheet of compressible paper having a plurality of substantially parallel, longitudinally positioned elongated openings therein, said openings being so spaced with respect to each other that they will form said wall with a plurality of openings therethrough;'end closures carried by said wall, one of said closures having means allowing the emission of contained powder therethrough; and a flexible outside covering for said device closing said wall openings'.

3. A laminated compressible powder dispensing device comprising a laminated body wall formed of a sheet of compressible substantially resilient Y material having a plurality of substantially parallel, longitudinally positioned elongated openings therein, said openings being so spaced with respect to each other that they will form said wall with a plurality of openings therethrough, said wall laminae being immovable with respect to abutting laminae; end closures carried by said wall, one oi said closures having means allowing the emission of contained powder therethrough; and a flexible outside covering for said device closing said wall openings.

4. A laminated compressible powder dispensing device comprising a laminated body wall formed of` a sheet of compressible paper having a plurality of substantially parallel, longitudinally positioned elongated openings therein, said openings being so spaced with respect to each other that they will form said wall with a plurality of openings therethrough, said wall laminae being immovable with respect to abutting laminae; end closures carried by said wall, one of said closures having means allowing the emission of contained powder therethrough; and a flexible outside covering for said device closing said wall openings.
